There is provided an antenna apparatus in a CDMA mobile communication system. A pair of pre-processors are assigned to each of n sectors for transmission and reception diversity. Each pre-processor has a transmission port and a reception port to separate a transmission signal from a reception signal. A pair of triangular antennas are assigned to each sector. In each triangular antenna, a transmission antenna unit transmits a transmission signal received via a transmission port in its sector in the direction of the sector, and a reception antenna unit, connected to the transmission antenna unit at a predetermined horizontal angle .theta., receives a signal directed to an adjacent sector and transmits the received signal to the reception port of a pre-processor in the adjacent sector.

L'invention concerne un appareil à antenne dans un système de communication mobile AMCR. Deux pré-processeurs sont attribués à un des n secteurs en vue de la transmission et de la diversité de la réception. Chaque pré-processeur a un point d'accès de transmission et un point d'accès de réception afin de séparer un signal de transmission d'un signal de réception. Deux antennes triangulaires sont attribuées à chaque secteur. Dans chaque antenne triangulaire, une unité d'antenne de transmission transmet un signal de transmission reçu par un point d'accès de transmission dans son secteur en direction du secteur, et une unité d'antenne de réception connectée à l'unité d'antenne de transmission au niveau d'un angle horizontal prédéterminé .theta. reçoit un signal dirigé vers un secteur adjacent et transmet le signal reçu au point d'accès de réception d'un pré-processeur dans le secteur adjacent.
